There are issues and risks that are brand new and not obvious. Fourth-generation development efforts make very different demands upon companies and management than do more traditional methods. So, what's the truth? The truth is that the rules of the game have changed. The press cites stories of huge applications that simply failed to run when they were put into production. And it will be very easy: ultimately, programmers and systems analysts will be used less, and end users will control their own destinies.Ĭritics of the relational approach warn that relational systems are inherently slower than others, that users who are given control of query and report writing will overwhelm computers, and that a company will lose face and fortune if a more traditional approach is not taken. According to the database vendors - the industry evangelists - developing an application using a relational database and the associated "fourth-generation" tools will be as much as 20 times faster than traditional system development.
